Lexan Polycarbonate Flat Sheet offer high impact strength
Bayer Makrolon Polycarbonate products give you a unique balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is a very long-lasting material. Though it features considerable impact-resistance, it's got reduced scratch-resistance and thus a hard coating typically is applied to polycarbonate eye protection lenses and polycarbonate exterior auto equipment. The properties associated with polycarbonate are similar to that of those of Acrylic PMMA materials, yet , polycarbonate is always stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and it has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools are required to be held at warm to high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without cracking. As a result, for small changes in shape, it can be processed and formed cold using sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be made from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent without heating.
Polycarbonate is commonly utilized in eye protection, as well as in other projectile-resistant optical type applications that would normally indicate the use of glass, but require much greater impact-resistance. Many different types of lenses are manufactured from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
